FAQ
What is the spelling of G#maj9?
G#maj9 is G#, B#, D#, F## and A#. The major seventh is F##, a double sharp, because the seventh letter over G is F.
Is G# major ninth the same as Abmaj9?
They are the same chord by ear. Abmaj9 is spelled Ab, C, Eb, G and Bb, which avoids the double sharp that G#maj9 needs.
Why does G#maj9 use B# rather than C?
In G# major the third is B#, because a third counted up from G must carry a B letter name. B# sounds identical to C, but the letter name keeps the chord stacked in thirds.

There are three voicings, two using a barre and none using open strings, covering frets 3 to 12.
Which scale matches G#maj9?
